reliability, which is required for FreeBSD systems that serve as servers. Unix's tree-like directory structure is very standard, that kind of file should be placed in that directory has a certain habit. Of course, in different UNIX, the location of the specific files also have subtle differences, in fact, in the process of UNIX development, the standard directory tree structure has several major changes, but the basic structure is the same. Because

Super User Root Superuser is the owner of Unix, has all the rights, so it is also very dangerous, improper use of super user power can cause irreparable damage to the system. Even though you don't need to share the system with other people for the FreeBSD system you use, do not use root to do day-to-day work. Typically, administrators operate only with ordinary accounts under normal circumstances and use superuser privileges only when necessary to pe

In FreeBSD systems, many settings require direct changes to the settings file, such as the system startup script rc.conf, the control terminal settings file/etc/ttys, and so on. Although most of the system's parameters can be set by the installer Sysinstall, changing the configuration file is more straightforward. And for administrators, only understand the configuration file is how to control the performance of the system in order to fundamentally so

Article Title: FreeBSD sets the minimum cpu operating frequency for powerd. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. After FreeBSD starts powerd, how does one ensure that the cpu frequency is not reduced to a low level, resulting in system stability or slow start

Record that FreeBSD, Debian, and CentOS are bound to multiple IP addresses-Linux Enterprise applications-Linux server applications. For more information, see the following. 1.

In traditional UNIX systems, DAC protection measures include file access mode and access control list, while MAC provides process control and firewall. The TrustedBSD program combines the core FreeBSD release with trusted security components that comply with the information technology security assessment standard (ITSEC. These components provide In traditional UNIX systems, DAC protection measures include file access mode and access control list, whil

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. If you have a FreeBSD, and you want to connect cvsup to the latest src after Microsoft's ISA or ms proxy, try:1) first, cvsup needs to be compiled and installed us

This article may be helpful if you think that a gigabit Nic on an intranet server cannot meet your switching needs.In fact, I have never thought about writing this article before, because I had an interview with a well-known domestic video website two days ago. I had the following question: "I will give you a server with four Gigabit NICs, how can I achieve the maximum 4G traffic output?" At that time, I did not think much about completing the job. After several days, I deployed the hadoop clust

HOST: WinXP sp3VirtualBox 2.2.2FreeBSD7.1-releaseI won't talk much about installing and using VBOX in XP. The Chinese interface is very simple and dumb. Note that VBOX only supports virtual hard disks with a fixed size not greater than 4 GB, so I will use 3.99 GB.Install FreeBSD7.1-release's ISO file, which is the same as normal installation.After the installation is complete, the original 3.99GB virtual hard disk is too small. We will mount another virtual hard disk in the VBOX. /Usr/ports occu

Rsync + SSH Incremental backup file in FreeBSD system There are two machines. One is called a server and the other is called a backup machine. How can we copy the server data to the backup machine on a daily or regular basis? The powerful functions of rsync will be used here. During each transmission, rsync checks the remote file list and transfers only updated files remotely. Therefore, it only takes a long time to run the first time, it will soon be

The DNS architecture under FreeBSD-Linux Enterprise Application-Linux server application information. The following is a detailed description. Generally, a computer only needs to configure domain name resolution and does not need to run the name server daemon process on its own. However, sometimes you need to set your own name server, in this case, you need to configure the Name Server BIND (Berkeley Internet Name D omain) under

I 've been tossing around for four days before and after, but it's really annoying.It is not difficult to configure the real VPN (PPTP) on FreeBSD. You only need 5 minutes to complete the configuration.Solved the problem. I fought with tun0 in half of the remaining 99% of the time and found that I made a low-level mistake.By mistake, I am fighting with ipfw in the other half of the time and found that the VPN connection mechanism is quite complicated.
